Abstract

PURPOSE:To make the loading of a cooling gas bomb in a guided missile unnecessary and reduce the size as well as the weight of the guided missile by employing high- pressure gas for cooling a sensor as booster upon launching the guided missile. CONSTITUTION:A high-pressure gas bomb 1 for cooling/launching is connected to a sensor cooling unit 7 through a cooling gas pipeline 4 and a reverse-flow preventing valve 3 is provided at the side of the high-pressure gas bomb 1 for cooling/launching or the cooling gas pipeline 4 while a sighting scope 13 is arranged at the outside of a launching tube 6. The high-pressure gas bomb 1 for cooling/launching supplied high-pressure gas until a guided missile 5 is launched and is injected against he sensor to cool it. A nozzle 2 is opened upon launching the guided missile 5 and the guided missile 5 is launched out of the launching tube 6 by the reaction of the injection of the high-pressure gas. Simultaneously with the ignition of the propulsion device of the guided missile 5, the high-pressure gas bomb is separated from the guided missile and the reverse-flow preventing valve 3 is closed whereby the reverse flow of remaining gas is prevented. The guided missile flies for several second and accomplishes the operating object of the same while securing functions under the condition of initial cooling.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a guided missile launcher, and more particularly to a portable, small and lightweight guided missile launcher for guided missiles.

[Conventional technology]

Conventional guided missile launchers have used dedicated gas or gunpowder as a booster for launching guided missiles.

FIG. 2 is a cross-sectional perspective view of a conventional guided missile launcher. The guided missile launcher shown in FIG. 2 is a small and lightweight guided missile launcher that is carried on the shoulder of an operator and guided toward a target in the air. The gunpowder 8 is ignited by a trigger 12, and a guided bullet 10 is fired.

In this case, the sensor unit 14 is disposed at the head of the inductor 10, and a sensor such as an infrared detector that is cooled to about 70°K (Kelvin temperature) is commonly used. The cooling gas cylinder 9 filled with high-pressure gas and containing a refrigerant for cooling cools the sensor of the sensor section 14 with its ejected gas.

[Problem to be solved by the invention]

The above-described conventional guided missile launcher requires a dedicated launcher in order to launch the guided missile, which has the drawbacks of an increase in size and weight and an increase in the number of parts.

[Means to solve the problem]

The guided missile launcher of the present invention has a high-pressure gas for cooling the sensor and a configuration used as a booster when launching the guided missile.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a partial cross-sectional perspective view of an embodiment of the present invention, in which a high-pressure gas cylinder 1 for cooling/launching, a gas outlet 2, and a guided missile 5 having a sensor cooling section 7 including a sensor in its head are disposed. is installed in the launch tube 6, the high-pressure gas cylinder 1 for cooling/firing and the sensor cooling unit 7 are connected by a cooling gas pipe 4, and the high-pressure gas cylinder 1 for cooling/firing of the cooling gas pipe 4 is connected to the sensor cooling unit 7.
The system is equipped with a check valve 3, and an aiming scope 13 is provided outside the launch tube 6.

Next, the operation of the embodiment shown in FIG. 1 will be explained.

The cooling/launching high-pressure gas cylinder 1 is connected to the sensor cooling unit 7 through a cooling waste pipe 4, and supplies high-pressure gas to the sensor until the guided projectile 5 is fired, thereby cooling the sensor. When the guided bullet 5 is fired, the ejection port 2 is opened, and the guided bullet 5 is fired from the launch tube 6 due to the reaction of the jet of high-pressure gas. At the same time as the propulsion device for the guided missile 5 is ignited, the high-pressure gas cylinder is separated from the guided missile, and the check valve 3 is closed to prevent the residual scum from flowing back. Guided missiles maintain their functionality in their initial cooling state, and fly for a few seconds to complete their operational purpose.

〔Effect of the invention〕

As explained above, the present invention uses high-pressure cooling gas as a booster for launching guided missiles, thereby eliminating the need to mount a cooling gas cylinder inside the guided missile.
This has the effect of significantly reducing the size and weight of guided missiles.
